WINDOW CHANNEL Original Filed Nov. 10, 1933 Reissued Nov. 8, 1938 UNITED STATES WINDOW CHANNEL Adolph Rydquist, Rochester, N. Y assignor to The Schlegel Manufacturing Company, Rochester, N. Y., a corporation of New York Original No. 2,037,487, dated April 14, 1936, Serial No. 697,464, November 10, 1933. Application for reissue August 25, 1936, Serial No. 97,833

Claim This invention relates to window channels such as are used for mounting a glass or sash in a vehicle, such, for example, as an automobile, aeroplane, motorboat, or the like. Under certain conditions, it is desirable to provide what may be termed a deep channel having more depth than the ordinary conventional window channel, so that the glass or sash may have a substantial movement transversely of the channel without actually leaving or pulling out of the channel. It is to such deep" window channels that the present invention particularly relates, although many of the features of the invention are applicable also to other forms of channel.

One object of the invention is the provision of a generally improved and more satisfactory deep window channel.

Another object is the provision of improved means for holding one or more cushioning elements in position on-the window channel.

, Still another object is the provision of a deep window channel having a sheet metal body which is relatively small in comparison to the depth of the complete channel.

A further object is the provision, in a window channel, of improved means for holding a cushioning element, and particularly of such means in connection with an element which is substantially in the plane of a side Wall of the channel and extends outwardly to form a continuation of the side wall.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawing:

Fig. 1 is a side elevation of a window channel constructed in accordance with one embodiment of the invention;

Fig. 2 is a transverse section taken substantially on the line 2-2 of Fig. 1;

Fig. 3 is a longitudinal section substantially on the line 3-3 of Fig. 1;

Fig. 4 is a diagrammatic view on a larger scale showing part of' the structure illustrated in Fig. 2;

Fig. 5 is a side elevation of a channel constructed in accordance with another embodiment of the invention;

Fig. 6 is a view similar to Fig. 5 with one wall of the channel broken away to show the interior construction Fig. 7 is a transverse section substantially on the line '|-I of Figs. 5 and 6, and

Fig. 8 is a view similar to a fragment of Fig. 7, on a larger scale, to illustrate details.

The same reference numerals throughout the several views indicate the same parts.

Referring now to the embodiment of the in-' 5 vention illustrated in Figs. 1 to 4 inclusive, there is shown what might be termed a deep channel member having side walls l0 and a back and bot tom wall ll, all formed preferably from a singlepiece of suitable material, such as sheet metal. 10 This channel-shaped member may be wider and deeper than the usual window channel, so that a channel I2 of the usual size may be embraced within the deep channel member and secured thereto by any suitable means such as the rivets 15 i3. This channel member I2 may be of any suitable known construction, such for example as that shown in Schlegel Patent No. 1,847,700, issued March 1, 1932, or that shown in Schlegel Patent No. 1,895,688, issued January 31, 1933, or 20 that shown in'Schlegel Patent No. 1,928,574, issued September 26, 1933, to mention only a few of the possible constructions already known to those skilled in the art. In this inner channel l2 may be any suitable cushioning means indi- 25 cated diagrammatically at 15, such for example, as the cushioning means shown in any of the above mentioned prior patents. Cushioning means in the form of relatively long stiff pile such as disclosed in the above mentioned Patent 30 No. 1,847,700, is frequently preferred and is here shown diagrammatically in the drawing.

The two side walls ID of the deep channel body preferably do not extend through the entire depth desired in the channel, but are terminated 35 somewhat short of the intended extreme outer edge of the channel and are provided with slits or slots 20 extending inwardly from the outer edge to subdivide a portion of the outer edge into a plurality of tongues 21 and 22. Alternat- 40 ing tongues, such. as those designated by the numeral 2|, may be displaced laterally in one direction, with the intermediate tongues 22 displaced laterally in the opposite direction. Then a cushioning element is placed between the 45 tongues 2| and 22 and held in place thereby.

The cushioning element comprises a woven body 25 which may be of flexible or semi-flexible material such as felt or a woven textile fabric of any suitable kind. Preferably it is a textile body 50 woven from weft strands 26 and warp strands 21 indicated diagrammatically in Fig. 4. Some or all of the weft strands 26 are preferably formed of metallic wire to stiffen the body, while some or all of the warp strands 21 may be woven 55 between the tongues 2| and 22, which are forced toward a common plane so as to clamp the edge of the cushioning element firmly between them,

i as is plainly apparent from Fig. 3 of the drawing.

The cushioning element body 25 may itself form the desired cushioning pads, or separate cushioning pads may be formed on one or both side walls of the body 25. Such cushi n n pads may be in the form of the relatively long'stifl pile disclosed in the above mentioned Schlegel Patent No. 1,847,700, or in the form of the cushioningmads disclosed in any of the other above mentioned Schlegel patents, or of relatively long uncut loops as disclosed in the copending application of Charles P. Schlegel, Serial No. 595,352, filed February channels, or in any other form known to those skilled in the art. Preferably, however, relatively long stifi pile is used to form the cushioning pads, and this pile may be formed substantially as disclosed in the copending application of Charles P. Schlegel, Serial No. 660,402, filed March 11, 1933, for Window channel. In this last mentioned ap plication, long stiff pile is applied to a woven base. woven in part from metallic wires, and this construction is' especially suitable in the present instance.

The weft strands 26 shown in Fig. 4 of the present drawing, may correspond, for example, to the strands 23 shown in Fig. 3 of the drawing of the last mentioned Schlegel application, these strands preferably being mostly or wholly of metal, while the non-metallic warp strands 21 of the present application may correspond to the non-metallic strands 2| in the last mentioned Schlegel application. The cushioning pad may be formed, as in the Schlegel application, by relatively long stifi pile strands 3| (corresponding to the pile 30 or 3] of the Schlegel application) woven into the body or foundation strands as disclosed, for example, in said Schlegel application, and held, for example, by weft strands 32 corresponding to the strands 22 of the Schlegel application. These cushioning strands 3| may be formed on one or .both sides of the body 25. If only on one inwardly from the inner side of the body 25 toward the mid plane of the channel, to provide adequate cushioning support for a window glass indicated at 34.

One or both of the outer edges of the cushioning elements 25 may be provided with a bead 31 formed of any suitable sheet material, such as sheet metal, bent to a rounded cross section and embracing a portion of the outer edge of the cushioning element body 25 and running longitudinally along this edge, as shown. The edge of the cushioning element may be somewhat enlarged, if desired, in order that the bead 37 may grip it more firmly, such enlargement being secured, for example, by the use of an enlarged warp strand 36 extending along the body 25 approximately at its edge. These beads 31 not only assist in holding the edges of the somewhat flexible cushioning elements straight and 26, 1932, 1'01 wlndow side, then they preferably extend true, but also provided a decorative finish for the outer edges of the channel when these edges are used in a position in which they are exposed to view.

The channel I2 is shown in dotted lines in Fig. 2. The cushioning pads II also cushion the sides of the window when it is in this position, and furthermore provide cushioning support for the window when it is moved slightly outwardly with respect tothe channel, from the dotted line position to the full line position shown in Fig. 2 of the drawing. Such a movement may be made to open part of the window for ventilating purposes or the like, as understood by those skilled in the art.

In Figs. 5 to 8, inclusive, of the drawing there is shown a modified embodiment of the invention which is preferred under tion now being described and the previous construction, is that the slits which form the tongues 2Ia and 22a, instead of being substantially parallel to each other to make substantially rectangular tongues, are at an angle to each other to makes tongues which are not rectangular. The tongues 2ia are preferably approximately triangular as shown, with relatively sharp points at their oute ends,

in the preceding case. By comparing Figs. 2 and 4 of the drawing with Figs. 7 and 8, it will be seen that the sheet metal I Ila in the latter figures is indicated as being materially-thinner than sheet metal ill in the former figures.

As previously stated, the cushioning pads may be formed on one or both sides of the cushioning known manner, as disclosed, for example, in the patents and applications above mentioned, but preferably are formed from relatively long stifi pile in the manner above referred to in connection with the pads 31.

When the channel is placed in a groove or rabbet oi the window frame of the vehicle to which it is applied, the pads "on the exterior of the cushioning element provide cushioning between the channel and sidewalls of the groove or rabbet, and thus prevent rattling or squeaking which might be caused by direct contact of the channel with the walls. Obviously such exterior cushioning may be applied to the form .of channel shown in Fig. 2 as well as to that shown in Fig. '7.

While certain embodiments of the invention have been disclosed, it is to be understod that the inventive idea may be carried out in a number of ways. This application is therefore not to be limited to the precise details described, but is intended to cover all variations and modiflcations thereof falling within the spirit of the invention or the scope of the appended claims.
